The temperature rise of hydro-viscous film in rotating parallel disks is usually controlled by imposing throughflow for keeping high film viscosity, but the Coriolis effect induced by throughflow can resist hydro-viscous transmission in return. In this work, the combined effects of Coriolis force and temperature-viscosity dependency on the hydro-viscous transmission are investigated. Firstly, the...
The imposed throughflow into rotating parallel disk system is to decrease temperature rise of hydro-viscous film flow, but the induced Coriolis effects are usually underestimated on torque transmission. The analytical expressions of thin-film parameters are obtained based on Navier-Stokes equations with the method of approximate analytical iteration. The Coriolis force and the corresponding influence...
This paper presents a new cutter-head driving system of tunnel boring machine (TBM) with hydro-viscous clutch (HVC) applied in order to improve the extricating performance, and a kind of theoretical methodology is proposed to analyze the extricating performance of HVC. Firstly, the Navier-Stokes equations are reduced upon the characteristics of oil film within HVC and the dynamical mathematical models...
